Definitions
- the invention concerns a cooler for gases generated from coal by gasification under pressure in accordance with the preamble to claim 1.
- the object of the present invention is to improve the generic cooler to the extent that the roof of the insert can be created by simple means.
- the pipes which extend parallel inside the sectors, can be combined into a gas-tight roof by means of intermediate webs of uniform width.
- the triangular spaces left behind the sectors are sealed off gas-tight by the crosstail butts that unite the pipes, pairs of which abut together at an angle.
- the uniform distribution of the pipes in the roof in one practical embodiment makes it possible in a simple way to join the pipes in another, interior, insert into the roof by means of T-shaped connectors.
- FIG. 1 is a longitudinal section through a cooler in accordance with the invention
- FIG. 2 represents the detail Z in FIG. 1,
- FIG. 3 is a section along the line III--III in FIG. 1,
- FIG. 4 represents the detail X in FIG. 3,
- FIG. 5 represents the detail Z in FIG. 1 in another embodiment of the invention.
- a cooler consists of a pressurized vessel 1 with an upper connection 2 and a lower connection 3.
- Upper connection 2 communicates with the outlet of a pressurized reactor, wherein a gas is generated by the gasification of coal. The gas is to be cooled in the cooler. The gasification residue in the gas is removed through lower connection 3.
- the wall of the housing is protected by means of an ash hopper 4 at the bottom of pressurized vessel 1.
- Insert 5 Accommodated in pressurized vessel 1 is a refrigerated insert 5 that contains additional plate-shaped radiating surfaces. These surfaces are, for simplicity's sake, unillustrated.
- Insert 5 is in the form of a regular polygon built up out of n slabs. Each slab consists of vertical pipes 6 that are united into a gas-tight wall by webs 7.
- a coolant is supplied through a collector 8 at the bottom of insert 5, flows up through pipes 6, and is removed through another collector 9 at the top.
- the coolant is water that is vaporized in the pipes in insert 5 and removed from second collector 9 in the form of a mxture of water and steam.
- the tapering bottom of insert 5 opens toward pressurized vessel 1.
- a gas-removal connection 10 Connected to the wall of pressurized vessel 1 at a level above the bottom edge of insert 5 is a gas-removal connection 10.
- Intake section 12 is comprised of some of the pipes 6 in insert 5, which are united by webs into a gas-tight wall of pipes.
- each sector inside roof 11 extend parallel one to another and to the vertical midline of each side of the polygonal insert 5.
- Pipes 6 are welded in conjunction with webs 7 into a gas-tight wall.
- the width of the webs matches the distribution of the pipes in insert 5 and roof 11.
- the sector-by-sector parallel orientation of pipes 6 leaves triangular spaces between the sectors.
- Each pair of pipes 6, which abut at an angle in the vicinity of these intermediate triangular spaces, is fastened together by a forged crosstail butt 13.
- Each crosstail butt 13 has two pipe connections at the rear to secure it to a pair of pipes, and tapers toward its closed forward end.
- Crosstail butts 13 are distributed along a straight line that slopes toward the longitudinal axis of insert 5 in such a way that the front end of each crosstail butt 13 is secured to the next crosstail butt between the latter's pipe connections.
- the conically tapering longitudinal edges of each crosstail butt 13 parallel the axes of the pipes in the adjacent sector of roof 11.
- Shaped onto each crosstail butt 13 at a right angle is a pipe connection 14.
- the pipe connections 14 on the aligned crosstail butts 13 communicate with a pipeline 15 that extends outside of intake section 12 into upper collector 9.
- elbows 16 extend into elbows 16 and constitute the wall of intake section 12.
- Elbows 16 project inward and create brackets that support a fireproof lining 17 for refrigerated intake section 12.
- Insert 18 has, like outer insert 5, a polygonal cross-section, with the sides of the polygons paralleling each other. Insert 18 consists of a gas-tight wall of pipes. The distribution of its pipes and the width of its webs equal those in insert 5.
- the pipes 6 in roof 11 are separated, and each accommodates the foot of a tubular T-shaped connector 19 that is welded to the accordingly separated pipe sections.
- Each pipe in interior insert 18 is fastened to the downwardly oriented web of a T-shaped connector 19, securing the wall of that insert into the roof.
